New non-woven paper in IJSS

Our latest journal paper entitled “In-situ X-ray study of the deformation mechanisms of non-woven polypropylene” is now published in the International Journal of Solids and Structures. This paper was authored by PhD student Naigeng Chen, MS student Simge Uzun, and research scientist Margaret Koker.  X-ray scattering and micro computed tomography  were combined with uniaxial mechanical testing to investigate the micromechanical mechanisms governing non-woven strength. These experiments were run on our custom experimental setup at the Cornell High Energy Synchrotron Source (CHESS). We found that the number density of bonds strongly influences the fiber kinematics and overall strength in these meltspun thermoplastics.
